'jPatented o'er. 1.2, 1909.

Application filed July 2, 1908. Serial No. 441,617.

To all whom it zay concern:

Be it knowi' that I, JOHN C. MIoIiAnLsoN, a citizen of the UnitedStates, residing at Charleston, in the county of Kanawha and State ofWVest Virginia, have invented certain newand useful Improvements inTrolley-Clips, of which the following is a specification.

This invention relates to electrical connections, and more particularlyto wire supports and has for its object to provide a trolley clip, of anovel and desirable type.

Another object is to provide a trolley clip which will be adjustableupon a wire with out the use of special tools.

Other objects and advantages will beapparent from the followingdescriptionand it will be understood that changes in the specific'structure shownand described'may be made within the scope of the claimswithout departing from'the spirit of the invention.

In thedrawings forming a portion of this specification, and in whichlike numeralsof reference indicate similar parts in the sev-. eralviews, clip engaged with av wire, Fig. 2 is a side elevation of thedevice. Fig. 3"is a-longitudia detailed view of the lock pin. n I

Referring now more particularly to the drawings, there is shown a clip.comprising a base section 10 comprising a wire engaging flange 11 havinga longitudinally extending groove 12 formed therein adjacent to one edgeand having a lateral extension 13 proj ecting from the side of theflange oppositely of the groove. Hinge flanges 14 are formed on eachside of the extension 13. A groove 15 is formed at the base of theextension 13,

extending in'spaced relation with the flange 11. The outer end portionof the extension 13 is formed into a cylindrical support engagingportion 16 'adaptedto bethreaded and engaged upon a suitable supportingmember or-otherwise engaged with a support. It will be-understood' thatthe, portion 16 may be given any form that may be desirable for variousfixtures with which it is desired to use the clip.

There is engaged pivotally with the base section 10 a lever men1ber17comprising a flange similar to the one 11 and having a groove 12 adaptedto register -,with the groove 12. The pivot member 17 is provided with alaterally extending tongue 19 (lirected outwardly at an oblique anglewith bar having its extensions 13 Figure 1 is an end view of thetheflange 18, and having a groove 15- thereacross disposed in registrywith the groove 15. The inner edge portion of the flange is bent to forma pivot portion 2Q which is engaged revolnbly within the flanges ll. (0-engaged between the grooves and 15' there is alock-pin 21 comprising atapered reduced end split and bent laterally as shown, to hold the pinsurely in engagei'nent with the clip.

In use, the base portion 10 and the pivot portion 17 being assembled,and the portion 16 being engaged with 'a support, a wire may be disposedbetween the flanges 11 and 18 and within the grooves 12 and 12' afterwhich the pin :21 may be inserted between the and 19 and d-rivenintightly to hold the wire securely engaged between the flanges, The splitend of the pin 21 spread laterally to ment from the clip.

As shown, the device is made from sheet material. bling the devicevistoform the rib on the section 18 and a groove in the inner edge of theflange 11 adjacent its junction with the shank 16. The ridge 20 is thendisposed in the groove, and the flange 14 bent thereover as shown. Itwill be apparent however, that numerous mechanical changes in'the construction shown may be made, and it will be understood that suchmechanical changes tending to facilitate the assembling of'the devicemay be inade within the scope of the prevent ts dlsei'igageclaims.

iVhat is claimed is:

is then- The preferable method of 'asseni- 1'. An 'articleof the classdescribed (-om- I prising a base flan'ge havin-g. a longitudinal grooveformed ad acent to one edge thereof,

and having alaterallyextending shank on its opposite side, said baseflange having hinge flanges on opposite sides of. the shank, a pivotflange carried by said base member having, a longitudinally extendinggroove therein adapted to register and cooperate with the first namedgroove in pinching engagement with a wire. said pivot flange havingportions bent to form a pivot rib engaged rcvoliibl'y with said hingeflange of said base mem er. and having also a laterally extendingportion disposed in registry with the shankand a locking-pin adapted for wedging engagement between said laterally extending portion and saidshank to hold said flanges in detachable engagement with n Univ-n ing alongitudinally extentli tr lle v clamp roinprising opposite clampinenihers SlfilnPQkl from sheet nnm: rial. said members having integrai.hinged portions tornierl thereon eoei'igagetl pivotall v and havingopposed grooves therein adapted for clamping engagementwith a trolleywire. said members having lateral extensions oppositely of the groove,ancl a pin adapted for \veclging engagement therebetween, one of saiclextensions being adapted for engagement with a support.
